Question 3303
A right triangle has sides of length $2\sqrt{2}, 6\sqrt{2}$, and $\sqrt{80}$ units. What is the area of the triangle, in square units?
Correct Answer Logic:
Legs are $2\sqrt{2}$ and $6\sqrt{2}$ because $(2\sqrt{2})^2 + (6\sqrt{2})^2 = 8 + 72 = 80 = (\sqrt{80})^2$. Area $= \frac{1}{2} \times 2\sqrt{2} \times 6\sqrt{2} = 12$.

Correct Answer Logic:
- Molar mass of $NH_4SH = 51\text{ g/mol}$. Initial moles $= 5.1/51 = 0.1\text{ mol}$.
- At equilibrium, moles of $NH_3 = H_2S = 0.1 \times 0.3 = 0.03\text{ mol}$.
- Using $PV = nRT$: $P_{NH_3} = P_{H_2S} = \frac{0.03 \times 0.082 \times 600}{3} = 0.492\text{ atm}$.
- $K_p = P_{NH_3} \times P_{H_2S} = (0.492)^2 \approx 0.242\text{ atm}^2$.

QUESTION #5572
Question 3306
What is the major product when $R-C\equiv N$ is treated with (1) $AlH(i-Bu)_2$ (DIBAL-H), then (2) $H_2O$?
Correct Answer Logic:
DIBAL-H (diisobutylaluminium hydride) at low temperature partially reduces a nitrile ($RC\equiv N$) to an imine intermediate ($RCH=NH$), which upon aqueous workup ($H_2O$) hydrolyses to give an aldehyde (RCHO). Full reduction with $LiAlH_4$ would give the amine $RCH_2NH_2$.
